Abstract
Mobile stations are classified into a first grouped station which is portable, and a second ungrouped station which is carried by a vehicle. A grouped station receives a part of the time slots of a paging channel relating to the group which the station belongs, and an ungrouped station receives all the time slots of a paging channel. A base station having a plurality of buffer cells (1-n) relating to each group, stores the queue of the paging signals in each buffer cell, and broadcasts the content of each buffer cell in the related time slot of the paging channel. A paging signal for a grouped station is stored in the related buffer cell, and a paging signal for an ungrouped station is stored in the buffer cell which has the shortest queue. Thus, a grouped station saves battery power because of intermittently receiving a paging signal, while keeping a short waiting time for an ungrouped station, and small call loss ratio.
